[PATCH v6 00/12] ClearFog Base static variant support

[PATCH v6 00/12] ClearFog Base static variant support

[Joel Johnson]

This patch series adds support for ClearFog Base static configuration,
as well as updating and fixing the ClearFog support for MMC and SPI
booting.

v2 changes:
  - updated against, and dependent on, https://patchwork.ozlabs.org/cover/1200324
v3 changes:
  - rebased against ClearFog runtime TLV EEPROM changes merged into mvebu/master
v4
  - adjust static SerDes configuration at runtime instead of #ifdef
v5
  - distinguish build-only config changes (SFP and PCIe/SATA) from
    runtime detectable config changes
  - retested SATA mode in PCIe slot with swap rx changes, confirmed
    working as presently patched. Only tested with ClearFog Base which
    only provides single channel, but Pro mechanism is parallel.
v6
  - address minor review feedback


Joel Johnson (12):
  arm: mvebu: fix SerDes table alignment
  arm: mvebu: solidrun: remove hardcoded DTS MAC address
  arm: mvebu: clearfog: use Pro name by default
  arm: mvebu: clearfog: initial ClearFog Base variant

[PATCH v6 01/12] arm: mvebu: fix SerDes table alignment

[Joel Johnson]

Tested on Solidrun ClearFog Base. Table alignment was:
 | Lane #  | Speed |  Type       |
 --------------------------------
 |   0    |  3   |  SATA0       |
 |   1    |  0   |  SGMII1      |
 |   2    |  3   |  SATA1       |
 |   3    |  5   |  USB3 HOST1  |
 |   4    |  5   |  USB3 HOST0  |
 |   5    |  4   |  SGMII2      |
 --------------------------------

After the change, it's correctly aligned as:
 | Lane # | Speed |  Type       |
 --------------------------------
 |   0    |   3   | SATA0       |
 |   1    |   0   | SGMII1      |
 |   2    |   5   | PCIe1       |
 |   3    |   5   | USB3 HOST1  |
 |   4    |   5   | PCIe2       |
 |   5    |   0   | SGMII2      |
 --------------------------------

[PATCH v6 02/12] arm: mvebu: solidrun: remove hardcoded DTS MAC address

[Joel Johnson]

Using a consistent hardcoded MAC address from the DTS file causes
issues when using multiple devices on the same network segment.
Instead rely on environment configuration or random generation.

Signed-off-by: Joel Johnson <mrjoel@lixil.net>

v2 changes:
  - reworked based on Baruch's run-time TLV EEPROM detection series
v3 changes:
  - rebased on mvebu merged run-time TLV EEPROM detection series
  - minor update to help test regarding runtime detection failures
v4 changes:
  - use runtime static config adjust instead of #ifdef in cases where
    hardware EEPROM detection fails or is disabled in build
    SPL size change for defconfig increases 36 bytes (122893 to 122929)
    SPL size change for defconfig+Base increases 60 bytes (122893 to 122953)
  - add placeholder support for EEPROM based Clearfog Pro, based on
    initial name confirmation from Baruch. I wanted to include the check
    at least in the patch for review to indicate expected usage to
    ensure that a Clearfog Pro EEPROM device boots correctly even if the
    image is built with Base static configuration. If there are other
    prerelease concerns and this should be added separately later, I'd
    be fine with that too.
  - Note that this approach *does not* currently provide any mechanism
    for EEPROM detected boards to have their SFP speed changed or switch
    between PCIE/SATA signalling. I'm assuming that will be done based on
    hardware detection, but confirmation/acceptance in review would be
    appreciated so it can be revisited if needed.
v5 changes:
  - only make Base variant adjustment based on runtime configuration
v6 changes:
  - print console message when falling back to static default; this
  would be nice to issue separate messages for the cause (no EEPROM
  detected, not compiled in, no matching product name) but that is
  better done as a separate changeset

There was some reasonable concern raised about duplicating config
entries within a board specific config file rather than making
board specific configurations within defconfig. This seems to offer
a more board localized mechanism to provide platform defaults for
core values. As mentioned in the review, this usage seems to match
the Kconfig documented intended usage. As noted at
https://www.kernel.org/doc/html/latest/kbuild/kconfig-language.html:
    "Default values are not limited to the menu entry where
     they are defined. This means the default can be defined
     somewhere else or be overridden by an earlier definition."

Given that there is some dependency variability with these values I
prefer keeping them as Kconfig values, but defer to maintainers.
Notably, for the ENV values in this and a later commit, I'm using a
pattern already in used several other board configs.

[PATCH v6 09/12] arm: mvebu: enable working default boot support

[Joel Johnson]

With the move to driver model usage, ensure that the required driver
support for SPI and MMC booting is available in SPL.

Tested on SolidRun ClearFog devices.

[PATCH v6 12/12] arm: mvebu: clearfog: Use Pro DT by default

Switch to explicitly using the Pro variant DT, which has been
available since Linux 4.11.

I separated out this change to the end of the series since it drew
questioning on prior review. I'd still advocate for making the change,
since especially with the additions of static variants and runtime
detection, it becomes easier from within a booted kernel to identify the
type and version of U-Boot image installed. Without making this change,
it becomes less direct to determine an actual Pro vs. Base, vs old
U-Boot image maybe supporting some hybrid variant configuration.

Even in the Linux kernel adding of the Pro DTS, it is indicated that it
was meant for backwards compatibility.

Except for cases where checking is done directly against the product
name from userspace, I don't see downsides even from a compatibility
perspective for not making this change. In cases where checking *is*
done from userspace, the broadening of the Clearfog product line would
seem to mean that userspace checking should be flagged as needing to be
udpated as well (or glob/regex matched as needed).

This patch generates multiple warnings on other MVEBU platforms. I've
dropped it for now in my upcoming pull request. Please rework the
problematic patches (missing in the pull request) and re-send.

Sure, I'm looking into the changes and will have a new series with the 
reworked patches in the next couple of days. The warnings really 
highlighted additional cleanup on mvebu booting and defaults in general 
which I'm taking a look at.

I'm not too familiar with the multi-target building, but have read up on 
and am currently using the buildman tool with arm and aarch64 toolsets, 
and building the entire mvebu target set (21 boards currently). Is this 
the best way to do the testing and building across multiple boards or is 
there a different way you'd like the testing to be done in the end?

Somewhat offtopic, what's the best location to which wiki issues should 
be reported? The page on Patches [1] still describes the old MAKEALL 
script. I hadn't found the script originally so skipped that step since 
it wasn't possible. This time, in digging further in source history I 
found the commit that removed it and referenced buildman. It would be 
useful for new contributors to update the wiki with a pointer to 
buildman if that's the desired replacement tool.

buildman is the correct tool for this. It can also automatically
download all necessary toolchains for other architectures.

This is outdated.

Could you please work on the wiki with the updated infos? That would
be helpful.

Thanks,
